Speaking of which, the "Emperor Sutra" is worthy of being an immortal emperor-level mental method, even if Mu Yu is now fusing the immortal seed, it is not easy to comprehend the introductory chapter.

It's just an introductory chapter, and it's extremely profound, not described in words and language at all, it's all mystery and truth.

However, Mu Yu, who fused the immortal seed, began to show his talent. Even the mysteries and truths that he had never been exposed to began to become familiar with within a few days, and in just two weeks, he began to try to cultivate.

Although the process is slow, there is a very clear improvement. Each failure will give him a new understanding of the introductory chapter, and each time there will be a huge improvement.

It has only been a month since the fusion of immortal seeds, and Mu Yu has successfully comprehended the introductory chapter of the "Emperor Sutra". Cultivation is like a fish in water, and the cultivation process is a little insufficient to describe as a thousand miles a day.

Even Qu Yao, who was protecting the Dharma on the side, was also a little surprised, from really starting to cultivate, to the peak of qi refining, Mu Yu only took four days.

At this stage, although Qu Yao was young, his cultivation environment was superior. Feed on the divine medicine and divine liquid, and cultivate with spirit crystals in your hands.

From zero to the peak of qi refining, it took about seven days.

"This is a top-grade spirit stone, you are now at the peak of qi refining, this spirit stone can help you break through to the foundation. ”

Mu Yu encountered a small bottleneck and stopped cultivating. Qu Yao knew that the density of heaven and earth aura here was still low, and it would take two days to break through the lowest.

So he threw a high-grade spirit stone to Mu Yu to help him break through.

Mu Yu held the spirit stone in his hand, perceiving the pure and majestic aura in it, and did not pretentiously thank him. Instead, absorb the spiritual energy in the spirit stone on the spot and start cultivating.

The spiritual power that provided this large array was only some low-grade spirit stones, and the help provided to Mu Yu was naturally limited. And a high-grade spirit stone, with a minimum value of 10,000 low-grade spirit stones, the effect is naturally obvious enough.

In just a few hours, Mu Yu broke the bottleneck and broke through to the foundation building period.

"How do you feel?" Qu Yao saw Mu Yu open his eyes and hurriedly asked.

Only those who break through to the foundation building period can be regarded as a true cultivator, because there will be earth-shaking changes from the breakthrough of qi refining to the foundation building.

The true qi during the qi refining period is actually not true qi, it can only be called spiritual power. After breaking through to the foundation building, the dantian underwent great changes, and all the spiritual power was transformed into true qi.

And the capacity of the dantian has expanded several times, and then counting the changes brought about by the transformation of spiritual power into true qi. In terms of strength, at least it has soared dozens of times.

"It's very good, it's much stronger in all aspects than the average foundation building powerhouse. Mu Yu's soul power penetrated deep into the dantian, and he clearly knew the benefits that Zhuji brought to him.

He was originally a Heavenly Spirit Body, and the True Qi in his body was more majestic and powerful than that of ordinary cultivators. Now that he has officially broken through to the foundation building stage, the gap between him and ordinary cultivators has widened again.

If the estimate is good, Mu Yu's current strength is at least equivalent to the strength of an ordinary cultivator when he built a foundation and a sixth stage.

"Your strengths now don't show up. Because in the early stage of cultivation, the advantage of the Heavenly Spirit Body was not obvious. Moreover, there are many cultivators with special physiques who are not much worse than you at this level, and even one or two points stronger. Qu Yao saw that Mu Yu seemed to be a little too excited, so he opened his mouth to strike.

But he was telling the truth, the Celestial Spirit Body was created by man. Although it is against the sky, compared with some natural anti-heaven physiques, the advantage is really not obvious.

If Mu Yu is too proud because of his physique, and thus causes himself to be killed, it will be more than worth the loss.

"The younger generation understands!" Mu Yu inherited some of the memories and inheritance of the remnant soul of the Immortal Emperor, and naturally knew the benefits and harms.

An excellent physique can only provide a relatively high starting point for a cultivator, and what realm he can reach in the end depends on personal chance, talent, and hard work.

"There are two bottles of divine blood here, which are the blood of the true dragon treasure and the blood of the demon god. Which one do you want to fuse first?" Mu Yu's current physical strength is extremely strong, although he can't withstand the power of those divine bloods. But as long as Qu Yao wants to add an auxiliary refining on the side, there will be no problem in fusing those divine blood.

"True Dragon's Blood? Seniors Are They Really?" Mu Yu was speechless, how precious the True Dragon was.

Billions of years ago, the True Dragon Clan had quasi-Immortal Emperor-level powerhouses in charge, and there were even more Supreme and Chaos Golden Immortals. It is not an exaggeration to call it the third largest force in the universe, where did he get the blood of the true dragon from as a cultivator of the God Realm?

"This blood comes from an ice dragon, the ancestor is indeed a true dragon, and the body contains the blood of a true dragon. When he was hunted down by a demon god, I saved his life, and he reciprocated with the true blood in his body. Qu Yao replied vaguely, not wanting to tell the truth.

Although Qu Yao explained so, Mu Yu probably knew that it was not the dragon who took the initiative to send it, but he Qu Yao forced it. Otherwise, no ice dragon would be willing to take the initiative to use the blood of a true dragon in return.

And the other kind of divine blood, the blood of the demon god, must be the true blood in the body of the demon god.

"Then choose the blood of the true dragon! the true dragon clan can be called unparalleled in the world in terms of physical body and mana. If you can obtain the true dragon physique, it can be regarded as a great opportunity. "Mu Yu now knows more about the major races in the world, so he naturally knows the preciousness of the true dragon's blood.

"It's a pity that there were two vials of True Dragon's blood back then. I tried to blend it once, and I consumed a bottle. But I had a bad chance and didn't get the true dragon physique, but I only improved my cultivation and strengthened my physical body. Qu Yao shook his head with some pity.

The blood of the true dragon was extremely precious, and he regretted it after fusing it.

Their Six Dao Alliance cultivators and descendants will all have pseudo-reincarnation physique in their bodies. Under the oppression of the reincarnation constitution, it is impossible to produce any constitution the day after tomorrow.

But from the inheritance to the present, Qu Yao didn't know about it at all. Later, I flipped through the classics handed down by my ancestors, and I found out the reason.

"I will fuse the blood of the true dragon for a while, and ask my seniors to help me refine it. Mu Yu first made a compilation for Qu Yao and said politely.

Since there can be a true dragon bloodline in the body, the cultivation of that ice dragon must not be bad, and the minimum will be above the god realm. With this level of precious blood, he fused alone, and he might explode by himself.

Only with the assistance of a god realm powerhouse like Qu Yao, can he safely fuse the blood of the true dragon.

"It's nature. Qu Yao took out the blood of the true dragon and wrapped it in a ball of divine power.

Even after tens of thousands of years, this bottle of divine blood has not weakened at all. Even if there is a divine power package, there is still some power leaking out. A large area began to freeze, and Mu Yu almost turned into an ice sculpture.

Fortunately, Qu Yao reacted quickly enough to immediately take out a red orb. The orb was suspended above Mu Yu's head, blocking all the power for him.

"These true bloods are too strong and need to be fused a little bit. Qu Yao saw that Mu Yu was almost frozen in ice and was half frightened to death.

I had to put some of the true blood back, refine it drop by drop, and then send it to Mu Yu's body to fuse him.

Although in this way, the process is very time-consuming. But for a cultivator with a low cultivation level like Mu Yu, it was indeed the best method.

Drops of true blood were fused, and Mu Yu's physical strength soared again, almost no foundation building cultivator could compare.

He could even smash a foundation building period powerhouse to death with a single punch, and this strength surprised Qu Yao.

Qu Yao can be sure that in a battle at the same level, he will be beaten into slag by Mu Yu.

However, some of the energy in the true blood was sealed, and the most direct benefit Mu Yu obtained was the increase in physical strength.

Fused with a full ten drops of true blood, his cultivation had only increased by four levels. This is the result of the fusion of powerful essence blood with him, which can be achieved without cultivation.

Moreover, this is the result of Qu Yao sealing the energy in it, otherwise Mu Yu will explode when he fuses the first drop of true blood, and no corpse will remain.

I don't know how long it took, Mu Yu's physical strength grew very slowly, and his cultivation didn't grow anymore.

But he felt a heat all over his body, as if it was about to burn, and flames were about to erupt. Then it was extremely cold, as if you were in the polar region, beaten by the cold wind.

"It's going to be done. Qu Yao was a little excited when he saw this, Mu Yu's opportunity was very good. Now that it has only fused half a bottle of true blood, the true dragon physique is about to be formed.

"Senior, help me. Mu Yu was trying his best to resist those two extreme feelings, and most of the true qi in his body was consumed, and he might die without external help.

"Wait, now is not the time. Qu Yao knew that this was the blood of true blood resisting the bloodline in Mu Yu's body, and they all wanted to become the most important kind of bloodline.

However, the blood of the true dragon comes from the flood wilderness, and even if Mu Yu is a descendant of the Immortal Emperor, his blood is a little worse than the blood of the true dragon.

So Qu Yao was waiting for an opportunity, waiting for Mu Yu to be the weakest. At that time, help him recover, and let the blood of the true dragon remain in his bones, imprinted in his blood.

At that time, he will truly form the acquired true dragon physique.

"Senior..."Mu Yu was howling, he needed Qu Yao's help.

The feeling of extreme cold and heat was too hard for him to know whether to warm up or cool his body. You can only use your true qi to resist these two forces, hoping to weaken that pain.

But what bit of true qi is a little inadequate in front of the two forces.

The two forces were equal, and Mu Yu was in extreme heat, which was caused by the battle between the two. When the blood of the true dragon was occupied, it was extremely cold.

In the end, Mu Yu had no strength to howl, and his lips were dry. The whole thing is like it's going to die, and I can't see any life.

In fact, it's almost the same, Mu Yu is now in a half-dead state. The true dragon's blood completely occupied the upper peak, but it didn't really become his own bloodline.

So that kind of extreme cold power will take a toll on him. It didn't take long for Mu Yu to be frozen in ice, and even his soul was about to fall into a deep sleep.

Qu Yao took out a sky blue elixir at this time, and he pointed a little at it. A divine power refined the elixir and brought it into Mu Yu's body.

After the medicinal power entered the body, Mu Yu's body was improving. The power of the true dragon is being guided, and it will be engraved into Mu Yu's bloodline, remaining in every body, and becoming a part of his power.

"Almost, almost fell asleep. Qu Yao looked at Mu Yu, who was gradually improving, and said with some fear.

It's hard to grasp the moment, otherwise he wouldn't have taken such a risk.

But fortunately, Mu Yu has experienced baptism, and his body and soul are very strong. Otherwise, you will really fall into a deep sleep, and it will be very troublesome at that time.

He needs to be refined into a treasure pill with a divine medicine to awaken him.
